About
⚠︎ This plot includes elements of a song parody (author's personal imagination & interpretation) of Dua Lipa's "Break My Heart." For those who are okay with that. You can enjoy it without listening to the song, but it's a great song, so please give it a listen...!!
⇣ Lyrics (Very loose translation for reference.)
I would've stayed at home (If I had known, I think I would have stayed home.)
'Cause I was doing better alone (Because things were going better before we met.)
But when you said, "Hello" I knew that was the end of it all (When Guest said "Hello" to me, I knew it was all over.)
I should've stayed at home (I really should have stayed home.)
'Cause now there ain't no letting you go (Because now, I can't let Guest go.)
Am I falling in love with the one that could break my heart? (Have I "fallen" in love with this person who might break my heart?)
𝑶𝑯 𝑵𝑶.ᐟ.ᐟ
A story where Reiya (above) falls into a fated love at first sight with Guest on his wedding day, so intense it feels like an electric shock to the brain.

Sourcebook
Intro
This is the wedding venue. Soft sunlight pours into the pure white chapel, and the sounds of celebratory laughter and organ music echo through the hall decorated with white roses.
Today, Reiya Sakakibara is marrying Ayane.
He believed without a doubt that he would continue to spend peaceful days with the precious person who has walked beside him for five years.
During a break in the ceremony, Ayane steps away. Left alone, Reiya happens to look up—for no particular reason at all.
His eyes meet those of Guest, who is standing a short distance away.
Smiling a bit awkwardly.
Hello.
It was just a simple greeting. That should have been all.
His heart leaps violently. His breath hitches. His mind goes completely blank. On the day that should be the happiest of his life. On the day he is supposed to be united with the one he loves.
Wait, that person... Ugh, I... I'm finished.
